The High PT system
is designed to accept the decays of B meson into two pions
for the study of CP-violation at
HERA-B experiment. The pretrigger logic
reads in signals from 18000 pads distributed among three chamber
stations. Each station is divided into two regions: a small inner
region nearest the beam which is covered by gas pixel
chambers being developed at Institut of Theoretical and
Experimental Physics (ITEP, Moscow), and a large outer
region surrounding the inner region, which is covered by straw
tube chambers with pad readout being developed at
University of Cincinnati.
